	<description>
		Exposes a set of tiles for a [TileSet] resource.
		Tiles in a source are indexed with two IDs, coordinates ID (of type Vector2i) and an alternative ID (of type int), named according to their use in the [TileSetAtlasSource] class.
		Depending on the TileSet source type, those IDs might have restrictions on their values, this is why the base [TileSetSource] class only exposes getters for them.

		You can iterate over all tiles exposed by a TileSetSource by first iterating over coordinates IDs using [method get_tiles_count] and [method get_tile_id], then over alternative IDs using [method get_alternative_tiles_count] and [method get_alternative_tile_id].

		<method name="get_alternative_tile_id" qualifiers="const">
			<return type="int" />
			<argument index="0" name="atlas_coords" type="Vector2i" />
			<argument index="1" name="index" type="int" />
			<description>
				Returns the alternative ID for the tile with coordinates ID [code]atlas_coords[/code] at index [code]index[/code].
			</description>
		</method>
		<method name="get_alternative_tiles_count" qualifiers="const">
			<return type="int" />
			<argument index="0" name="atlas_coords" type="Vector2i" />
			<description>
				Returns the number of alternatives tiles for the coordinates ID [code]atlas_coords[/code].
				For [TileSetAtlasSource], this always return at least 1, as the base tile with ID 0 is always part of the alternatives list.
				Returns -1 if there is not tile at the given coords.
